I seem to have hit a strange bug in the Wireguard implementation.
When I try to set the description I this message "interface description is too long (limit 100 characters)".
set wireguard wg0 description "A"
When I then try to remove the wg0 interface I get this Traceback.
Traceback (most recent call last):
File "/usr/libexec/vyos/conf_mode/wireguard.py", line 316, in <module>
apply(c)
File "/usr/libexec/vyos/conf_mode/wireguard.py", line 225, in apply
cnf_descr = c['interfaces'][intf]['descr']
KeyError: 'descr'
